including geometrical design characteristics, environmental and traffic specifications, by multiple
regression analysis. The main objective of this paper is identification of problems associated with
the safety issue of road networks by application of accident prediction models. Data from previous
accidents were used to develop the models.
Results of this study showed that the rate of road accidents is to a large extent dependent on the rate
of traffic volume. Type of road and land-use are other important factors influencing the number and
intensity of accidents. The mountainous roads in this respect require special attention regarding
their safety factors. The quantitative rate of road safety upgrading has also been specified by adding
traffic lanes in road networks.Accident Prevention, Highways, Traffic, Safety112119http://ijce.iust.ac.ir/browse.php?a_code=A-10-112-15&slc_lang=en&sid=1Mahmoud Saffarzadehsaffar_m@modares.ac.ir180031947532846005853180031947532846005853Yes
